To all whom it may concern:

Be it known that I, THOMAS A. SAMMONS, citizen of the United States, residing at ayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Automatic Cut- Oii' Valves and Faucet Mechanisms; and I do declare the following to be a full, clear, and exact description of the inveiaion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompan ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in valve and faucet mechanisms. The primary object of the invention is to provide quick and convenient means for shutting- 011 the flow of water when it becomes necessary to remove a faucet for any reason.

Preceding a more detailed description of my improvements, reference is made in gen eral terms to the accompanying drawings, in which Figure 1 is an elevation of a bih or faucet part of which appears in section and in which my improved cut-oil valve is shown in the portion of the faucet between the entrance of the inlet pipe and the valve of the faucet. ig. 2 is a sectional view showing a modi ication of the union which connects the automatic shut-oi'i' valve with.

the bib. Fig. 3 is an elevation of the Hi0tlificatwn shown in Fig. 2, and Fig. l is an elevation of a steam cock with my automatic shut-0fli valve applied thereto in a manner similar to Figs. 2 and 3.

In a detailed description of my improvements, the same rcieroime characters will denote corresponding parts in the several views of the drawings.

Referring to Fig. 1. common form o'l cock with a union or coupling member 18 which forms a connec tion between the inlet end of the cool: and. the intake fitting 21 which connects with the supply pipe. It will be observed that the/fitting}; 21 is in the form of an elbow which screws onto the coupling-1' member l8. The shut-off valve 11 lies horizontaily within the connection 18. The automatic shutoff valve 11 is in the form of a puppet valve and the normal position of said valve is open as shown in Fig. 1 it being held in this illustrates a;

such position by the end oi the faucet when the latter is screwed onto the coupling member 18. The said shut-elf valve provided with guide extensions in the form oi. radial veins 12. The veins 12 are reduced in diameter or cut away to provide a suitable space for the coil spring- 1.9. It will be observed that the spring 15) is mounted on the valve directly and is inclosed between shoulders 20 of the veins 12 and the inwardly extended flange at the end of the union ll. It will be observed from Fig. 1 that the shut-off valve is held oii' of the seat in the end of the union 18 and the spring 19 is under compression. When the bib is detached, the shut-0ff valve will be imn'iediately thrown to its seat by the expanding eflect of the spring. Fig. 2 illustrates a modification of l*ig. l in which the connection between the inlet end of the cool; and the supply pipe is effected through a union or coupling; 2 and to one end of which the inlet end of the cock is tapped and on the other end oi which the supply pipe is connected by c):- tcrior screw threads. The cut-01f valvo ll in this case seats against the seat :25 on the end of the coupling E-Z l, and the spring" ltl is mounted upon the valve wins .i in a manner similar tol ig. 1. in Fig. the shutoff valve 11 is shown on its seat, the cock having been partially unscrewed from the coupling 24:. 'Fig. 4: illustrates a common form of pct-cocl 27 to which the shut-oii' valve is applied by a union 26, which is similar to the union iiustrated in Fig. 9-.

ilavin r described my invention in detail, the operation is as follows: With the shutoff valve attached to a supply pipe. as shown in Fig. l for example. the volume of water to the faucet icnt of the faucet nuamber in engage ment with the annul: r shoulder oi. the ecu-- p ling lbw and the wingcnd or the shut-off valve itself. The watrr is shut oil alto- .c'ethcr when the ilisrngagoineut o1 said faucet member with said sbui.-otl valv'e tahcs place. 7

Ha ting (:lcscribcd my invention, .l claim:

it faucet having a valve therein oootrolling the outlet therefrom a coupling menu bar receiving: the inlet end of said faucet and having an inwardly extending image forming: a valve seat. a puppet valve carried by said. coupling; member havizr' a series oi is regulated by the adiust ill llil

elongated guide extensions which are reduced in diameter for a portion of their length, a spring mounted on the reduced portions of said guide extensions between 5 the shoulder thereon and said flange, said guide extensions being adapted to be engaged by the coupled end of the faucet and to he maintained in a position to hold the valve open, and said spring being adapted to exert a force to close said Valve when 16 disengaged by the coupled end of the faucet. In testimony whereof I afiix my signature, in presence of a Witness.
